Application fiiea May 10, 1919. seriaiNo. 296,109.

To all 'witam it may concern:

Be it known that I, EWELL W. PENDER- GRAM), a citizen of the UnitedStates, residing at Vicksburg, in the county of VVarren and State ofMississippi, have invented new and useful Improvements in SashAttachnients, of which the following is a specification. o Thisinvention relates to sashes, the object being to provide an attachmentfor balancing window sashes without the use of the usual sash weight.

Another object of the invention is to provide a sash attachment by meansof which a sash, that is, the upper and lower window sash, will act tobalance one another, to eliminate the use of weights and to provide fora simultaneous movement of both sashes, so that when the lower sash israised, the upper sash will be lowered to provide proper ventilation.

With the above and other objects in view,

the invention includes the following novel features and details ofconstruction, to be hereinafter more fully described and illustrated inthe accompanying drawings.

In the drawings:

Figure 1 is a fragmentary sectional View illustrating the application ofthe invention.

Fg. 2 is a detail elevation of the attachment looking at the reverseside from that shown in Fig. l.

F ig. 3 is a sectional view on the line 3- of Fig. 1.

Fig. 4; is a similar view on the line 41-4 of Fig. 1. p

Fig. 5 is a sectional view on the line 5 5 of F ig. 1.

Fig. 6 is a sectional view on the line 6-6 of Fig. 2.

Fig. 7 is a bottom edge view of the attachment. i

Referring to the drawings in detail, like characters'of reference denotecorresponding views throughout the several views.

In illustrating the use of the invention, there is shown at 10, aportion of a window casing, the upper sash being indicated at 11 and thelower sash at 12.

The invention comprises a plate 13, which is preferably rectangular inshape and is provided with openings 14 for the passage of screws oranalogous fastening devices,

Vor lowered position.

ings 19,' which are surrounded by inclinedV guides 20. These openingsand guides are formed by slitting the plate 13 at a point indicated at21 and pressing the material of which'the plate is formed inward, asshown in F ig. 4, so that the chain 18 will pass along the guides 20 andthroughv the openings 19 and have one of its ends connected to the uppersash 11, and its other end to the lower sash 12. It is, of course,obvious that one of these devices will be positioned Vupon oppositesides of the sash frame orV casing, and that one sash will act as acounter-balance weight for the other sash, so that the said sashes willremain in any desired raised By connecting the sashes in the mannerdescribed, a movement of one sash will cause a simultaneous movement ofthe other sash, so that should the lower sash be raised, the upper sashwill be p correspondingly lowered and thereby insure proper ventilation.i

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is here; in reserved tomake such changes as properly fall within'the scope of the appendedclaim.

Having described the invention, what is claimed is A sash attachmentcomprising Va plate
